Ian McDiarmid plays Dr Henry Pickerskill, a teacher at Haunchurst College for Boys in the days when it had boarders, icily remembering former pupils. Today, Patrick Trumball (Toby Longworth) who was fascinated by thunderstorms and lightning. What Dr Pickerskill spotted was that Trumball, an unusual child, also possessed a photographic memory which came in handy when the school's dodgy accountant blamed Pickerskill for a fraudulent tax return. Written and produced by Andrew McGibbon, this (all too short) series restores cynicism's good name.
